It contains adding a large binary file, which I would like to avoid to push to our main repository. How can I remove that from the series of commits? A command-line solution, please, if possible. Cheers - Gergely ``` ## Jeff King, 2011-05-04 08:45 Subject: Re: removing a commit from a branch Message-ID: <20110504084502.GC8512@sigill.intra.peff.net> URL: https://gitlist.dev/e/20110504084502.GC8512%40sigill.intra.peff.net In-Reply-To: ``` On Wed, May 04, 2011 at 10:35:08AM +0200, Gergely Buday wrote: > I have a problematic commit in a series of commits on a branch.

A command-line solution, please, if possible. Removing it will involve rewriting history, which can create headaches for people who have built on that history (they will need to rebase their commits on the rewritten history). But if that's OK, then the command you want is filter-branch. See "git help filter-branch"; in particular, the EXAMPLES section contains commands to do exactly what you want. -Peff ``` ## Gergely Buday, 2011-05-04 08:55 Subject: Re: removing a commit from a branch Message-ID: URL: https://gitlist.dev/e/BANLkTi%3DpVMrK8PM8s9MagN12FxMZ_%3DuAVw%40mail.gmail.com In-Reply-To: <20110504084502.GC8512@sigill.intra.peff.net> ``` > Removing it will involve rewriting history, which can create headaches > for people who have built on that history (they will need to rebase > their commits on the rewritten history). I did not push to any other repo yet, so this should be OK. - Gergely ``` ## Peter Krefting, 2011-05-04 09:17 Subject: Re: removing a commit from a branch Message-ID: URL: https://gitlist.dev/e/alpine.DEB.2.00.1105041014480.16939%40ds9.cixit.se In-Reply-To: ``` Gergely Buday: > I have a problematic commit in a series of commits on a branch.

A command-line solution, please, if possible. If the branch is simple (no merges and such), I'd use "git rebase --interactive branchpoint" (where "branchpoint" is where the branch is rooted), or "git rebase --interactive problematic^" (where "problematic" is the commit you want to edit, note the trailing "^" to start from its parent commit). Then change the "pick" for the problematic commit to "edit", run the rebase, fix up the commit by using "git rm" and "git commit --amend" when it pauses, and then let it finish using "git rebase --continue". "git --help rebase" for more information. -- \\// Peter - http://www.softwolves.pp.se/ ``` ## Dirk Süsserott, 2011-05-04 17:53 Subject: Re: removing a commit from a branch Message-ID: <4DC192A0.6010808@dirk.my1.cc> URL: https://gitlist.dev/e/4DC192A0.6010808%40dirk.my1.cc In-Reply-To: ``` Am 04.05.2011 11:17 schrieb Peter Krefting: > Gergely Buday: > >> I have a problematic commit in a series of commits on a branch.

Just do: $ git rebase --interactive problematic^ Again, notice the ^ after "problematic" An editor pops up with the history since problematic's parent, i.e. "problematic" is the first item in the list. Simply delete the line with the "problematic" commit. It should be the first line. Save the file, exit the editor. That's it.

I've a mailer problem (was: Re: removing a commit from a branch) Message-ID: <4DC1A519.3070907@dirk.my1.cc> URL: https://gitlist.dev/e/4DC1A519.3070907%40dirk.my1.cc In-Reply-To: <4DC192A0.6010808@dirk.my1.cc> ``` Sorry, I know, this is no Thunderbird board, but I guess other people use this client as well. When I write a message, it wraps at col 72 (or so). When I see my post in the list, it isn't wrapped at all. Only one long line per paragraph. That's inconvenient for the list and I'd like to avoid that. How do YOU do that? I'm using Mozilla Thunderbird 3.1.10 for Windows (which is the latest, I think). Again, I'm sorry about posing such an off-topic and non-git question, but probably someone has the same prob (or -- even better -- has had resolved it). Cheers, Dirk ``` ## Øyvind A.

There is a section on how to set up Thunderbird and other mail clients in Documentation/SubmittingPatches in the git.git repository which you can read here: http://repo.or.cz/w/git.git/blob_plain/HEAD:/Documentation/SubmittingPatches Regards, Øyvind ``` ## Dirk Süsserott, 2011-05-05 18:59 Subject: Re: Sorry, completely off-topic.
